How it works
Step 1: Gather information from the user's message — product, platform, current situation, and goals.
Step 2: Ask all follow-up questions at once in multiple-choice format. Allow shorthand answers (e.g., "1b 2c 3a").
Step 3: Conduct research and analysis using the framework and methodology below.
FNSKU Labeling System
- FNSKU definition: A unique identifier assigned by Amazon to each seller SKU, used for inventory tracking at fulfillment centers.
- Labeling requirements: Must cover the original product barcode. Apply to a flat surface, not to curved or wrinkled areas.
- Specifications: 1"x2" size, 300+ DPI print quality to ensure successful scanning. Sufficient white space is required around the barcode.
- Barcode covering: If the product already has a UPC/EAN, the FNSKU can be applied directly over it. If there is no barcode, an FNSKU label must be attached.
Packaging Compliance Framework
Amazon packaging requirements are based on two core principles: product protection (preventing damage during shipping) and worker safety.
- General requirements: All items must have a scannable outer packaging barcode.
- Bare products (e.g., hardware): Must use a clear polyethylene bag with a suffocation warning label and barcode.
- Fragile items: Require bubble wrap or foam packaging, clearly marked "Fragile."
- Products with sharp edges: Protective caps must be added.
- Liquid products: Require leak-proof sealed packaging.
- Multi-packs: Must use manufacturer tape or specific labels to prevent separation.
- Weight limit: Standard cartons maximum 50 lb/23 kg. Exceeding = extra fees or rejection.
Shipment Plans and Carton Optimization
- Shipment plan: Amazon assigns fulfillment centers based on inventory capacity and demand. The system may split shipments across multiple centers.
- Carton packing optimization: Maximize carton utilization within weight/size limits to reduce unit shipping cost.
- Fee structure: Standard-size and oversize items have different rates. Large items require precise calculation.
Prep Fee Avoidance Strategy
- Prep service fees: $0.30-1.50 per unit depending on prep type (labeling, bagging, bubble wrapping).
- Self-Preparation vs Outsourcing: Compare labor costs, equipment investment, time efficiency, and quality consistency.
- Rejection Risk: If preparation is too complex or the product condition is poor, Amazon may reject the entire shipment or dispose of the inventory.
Analysis of Common Root Causes of Rejection
- FNSKU unscannable: Poor print quality, damaged labels, incorrect placement.
- Packaging damaged/missing: Packaging damaged or missing during handling.
- Oversized/overweight cartons: Exceeding standard limits.
- Missing safety labels: Choking warnings, sharp edge warnings not attached.
- Multi-pack separation: Items separated due to improper sealing.
- Mismatch: Product does not match the shipment plan declaration (incorrect size classification).
- Missing carton labels: Unable to identify the shipment destination.
Data Sources
- Obtain product-specific specifications from the Amazon Seller Central FBA preparation requirements page.
- User-provided: product type, size classification, target market, barcode status.
Limitations
- FBA requirements vary by product type and change frequently — always check the latest guidelines.
- Special categories (hazardous materials, lithium batteries, liquids, food) have additional compliance requirements.
- Preparation fees add significant costs for complex preparation items.
- Rejection may result in inventory disposal — significant financial loss.
- Shipping costs vary depending on carton utilization efficiency.
Step 4: Provide structured, actionable output with specific recommendations rather than vague guidance.
Output Format
